Specification of Letters Patent.

Patented Apr. 28, 1914.

Applicationled May 13, 1912. Serial No. 697,052.

To aU whom, it may concern:

Be it known that I, VIGENTE FONT Y AMA- DoR, a citizen of the Republic of Cuba, residing at Vedado, Twenty-third street, Habana, in the Province of Habana and Republic of Cuba', have invented certain new and useful Improvements in Type Vriters, of which the following is a specification.

This invention relates toy certain novel and useful improvements in manifold attachments for typewriters.

A In carrying outl my invention, it is my purpose to 'providean attachment or device which may be applied to any of the standard makes of typewriters, and by means of which the process of Writing both the origiynal and carbon sheets may be proceeded with continuously and without the necessity of the operator losing time by stopping to change the carbone and paper sheets.

Still a further object of my invention is.

I to provide a simple, compact,l convenient and eilicient attachment -by means of which theddesired number of copies may be rapidly ma e.

With the above recited objects and others of a similar nat-ure in view, my invention consists in the construction, combination and arrangement of parts set: forth in and falling within the scope 'of the appended claims. f

In the accompanying drawings, like characters of reference indicate like parts in'V all the views, and Figure 1 is a View in 'side' elevation of an attachment embodying `my invention, this view illustrating a machine v for making a single carbon copy. Fig. 2 is a front view thereof. Fig. 3 is a diagrammatic view showing a form of machine for making a plurality of carbon copies. Fig. 4 is a detail view of one of the rollers. Fig. 5 is a View of one end thereof. Fig. 6 is a View of the opposite end. Fig. 7 is a' view in side elevation of the upper end ofone of the' standards. p

In the present instance, I have shown my attachment as embodying a frame designed to be mounted upon the ordinary typewriter carriage, and carrying a plurality of cylinders or rollers for the continuous sheets of paper and carbon, said sheets running around the ordinary roller or platen of the typewriter;

Referring now to the accompanying drawings in detail, the numeral 1 indicates the ordinary typewriter roller provided wlth a series of vertical arms or standards 4 preferably arranged in pairs, these pairs of standards or arms supporting the carbon carrying and paper carrying rolls as clearly shown in Figs. 1 and 2.

The numeral 5 designates a cross bar or4 plate of the carriage, while at 6 and 7, I have shown guide plates extending across the carriage, and arranged adjacent to the typewriter roller or piaten to ldirect the paper sheets and carbon sheets thereto, while 8 indica'es a hood plate or guide arranged above the platen or roller.

Referring now especially to Figs. 1 and 2, the numeral 9 designates a roller journaled in the rear pair of arms 4 and adapted to receive one end of the continuous carbon sheet or roll C, said carbon running forward and around the typewriter roller 1, and thence up to the second carbon roller 9, jcurnaled in the forward pair of arms 4. Thestud shafts l1 and 11 of the rollers 9 and 9 seat in slotted bearings 12 and 12 in the rear and forward pairs of arms, 'respectively.

The numeral 10 designates a roller for the paper P similarly journaled in the lower portion of the intermediate pair of arms 4, while the numeral 10 designates a roller for the second roll of paper P journaled likewise in the upperendportion of the intermediate pair of arms 4. The stud shafts for the rolleil 10 are indicated at 14 and seat in the slotted bearing 15, while t-he stud shafts for the lower roller 10 are shown at 14 and seat in the slotted bearings 15. As all. of the four rollers, that is to say, the two carbonrollers and the two paper rollers. are similar in construction Aand are provided with like tensioning .means for pro erly tightening or tensioning the paper andpcarbon sheets the description of one of the same hereinafter given is applicable to all. The shaft of. each roller is provided at one end with a toothed wheel 16 as shown in Fig. 7

against which bears ,a smaller roller 17 carried at' the free end of the pivote'd arms 18, while 19 designates a U-shaped leaf-spring connected at 2O to the adjacent arm and nozmally holding the roller 17 in contact w1V h the toothed wheel by 'bearing against the pivoted arm. Each carbon roller is further provided with a longitudinal groove approximately semicirculai'- in cross section and shown at 20 designed to receive a rounded bar 21. pivoted at onevend as at 2g; the outer surface of the bar lying flush with and forming a continuation of the periphery .of the roller. The opposite end of the rod carries a small pin 23 with which engages the bill of the lockingr hook 24 pivv.oted at 25 and normally thrown into .non-

loeking position b v the U-shaped spring 26.

27 designates a lockingY lever pivoted at 28 and adapted to bear againstA and hold the hook in locking` position. lVheu placing the carbon' paper on the rolls. the lever 27'is depressed so that .the hook thrown out 0f engagement withv the pin by means of thel spring74 thereby enabling' the rod to be lifted so that the end ot the carbon sheet may be inserted between the rod and the' rolls. y

The numeral Q8 designates a roller bearing: against and transmitting motion to the carbon roller 9', said roller 28 in turn resheet are po 1 veeivi'ng motion from the paper roller 10 -against whlch it bears. In order to malntaiu this roller 28 in proper position and under the necessary tension. I connect to each en d of the shaft thereof, one end of a spring Q9 the opposite end of each spring carrying a hook -30` for connection with the' ,keeiwrv bolt 3l in the adjacent' side ot' the frame member 4.

From the above description taken in eonneetiou with` the.accompanying drawingsi the construction and manner of en iployine'v my inventionwill be readily'appm-ent. v 'lhe original, paper sheetaud tlie sei-ondI paper 'attei being' passed around the typewriter platen ivi-th lh(l -arboi runningF therebetween. the ends are allowed to rim tree in the usual manner.- The paper-is also 'further toi-medi,

otfrolls and preferably 's eored or perforated transvorsely'at propel' distant-es to lornr the hr'oper lnzth oi" the sheets. vThe marhine is 4 now opera-ted in'pthe usual manner an`d 'as t-lie.\\'ork progresses. the paperand carbon are drawnott' tluir-respeelive feed rolls. the earbon beingr rolled on thereeeiving rol 9 so that when the reel 9 is emptying and the carbon isJrOlled entirely upon the reel 'WQ the latter' can-ho substituted orfexchang'ed with the reel'9,.and the operation Continued as before.

In Fig., 3 T have illustrated. diagram# -matieally a slightly modified v arrangement wherein-a plurality of second or carbon' sheets may be written. lnthis. casein adtioncd as'shown im Fig'. l. and

dition to the carbon reels 9 and 9 and the two paper rolls 10 and 10, I employ an additional pair of paper rolls 10 and 10".

The carbon sheet C running from the roll 9.

passes over the guide roller 32 and between the paper from the rolls 10 andL 10 around the typewriter platen 3, thence around the guide rolls 33, 34 and 35 to the `truide roller 36, thence between the paper rolls 10 and 10 around the typewriter platen again, thence between the tension roller QS and ythe guide 33 around the guide rolls 3l, 35 and 37, thence between the runs of paper coming from the rolls 10 and 10 aroundA the typewriter platen once again and up to the, carbon roller 9. From this it will be 4seen that any suitable number of paper rolls inay be employed depending upon th'e number of copies it is desired to make.

' It will be seen that I have provided an eX- l ceedingly simple, yet convenient device vwhereby the writing may be done continu#A ously and without the necessity of the operv ator stoppingto frequently change the car-1" bon sheet and to substitute new paper sheets.'

While I have herein shown and described the preferred embodiment of my invention by way ot' illustration, I wish it to be understood that I do not routine myself to all the precise details o t` construction herein set,

l'ortln'as modification and variation may be made without departingr from the spirit of rolls mounted on the intermediate stmidards and.` arrangedy one aloovel the other` and atensioned'roller arranged to bear against. the` uppermost paper roll and the ,carbon ioll arried bythe front standard,2said tensioned roll'er transmitting motion from the. papen roll't'o said -carbon' roll, and guide plates for directing the carbonand the paper to andaround the typewriter platen',
